The study room was located on the second floor of the Beke Family's house.
Since it was unsure if there were still ghosts lurking outside the door.
Koslin sawed a hole in the floor of the study, big enough for one person to pass through.
Han Dong and Koslin continued as a team, descending through the hole.
The hole led to a storeroom on the first floor...
Captain Cass and Fiya formed another team. Fiya provided various buffs with Holy Light to maximize Cass's 'pollution resistance'. At the same time, Cass could also apply the BUFF 'Power of the Crusaders' to himself.
While enhancing his physical attributes, it also increased his willpower, greatly reducing the effects of pollution on the brain.
The first step of the plan was for Cass to confront the ghost lurking in the mansion directly.
During the time Cass bought, all the team members would scatter and surround the 'ghost' from different angles, attempting to take it down as quickly as possible.
